Prevent Scrolling of Parent Element: An Alternative Solution
When working with a "floating toolbox" with scroll functionality, it can be frustrating when scrolling within the box triggers scrolling of the parent element. This behavior can be mitigated by preventing the scroll event from propagating.
However, the accepted answer while effective in other browsers, faces limitations in Internet Explorer. To address this, an alternative solution is necessary.
This solution centers on intercepting the mousewheel event using jQuery. Based on the event's delta, we determine whether the scroll is scrolling up or down.
If scrolling down, we check if the delta would exceed the scrollable area. If so, we prevent the event's propagation and set the scrollTop to the maximum value. Similarly, if scrolling up and the delta would push the scroll past the top, we prevent propagation and set the scrollTop to 0.
By handling the event directly in this manner, we prevent the unintended scrolling of the parent element, even in Internet Explorer. This ensures that the scroll event remains confined within the designated element.
